PUMP.

SPECIFICATION forming part of Letters Patent No. 301,045, dated June 24,1884.

Application filed January 26, 1884. (No model.)

.To all whom it may concern:

Be it known that we, WILLIAM H. CLARK and WILLIAM J. CLARK, both ofSalem, Columbiana county, Ohio, have jointly invented a new and usefulImprovement in Pumps, of which the following is a specification.

Our invention, while applicable to pumps generally, is more particularlydesigned for that class of portable pumps that are employed to emptyVessels containing burningfluid, and known commercially as fluidpumps.

Our improvement relating exclusively to the expanded top chamber or headof the pumpbarrel and its discharge-spout, the description and claimswill be restricted to those members.

Our pump-head or top chamber is so formed, arranged, and constructedthat part of it also serves the purpose of a spout or dischargenozzle,and thereby obviates the necessity of a separately manufactured andattached spout, which, as commonly made and attached to thepump-chamber, has heretofore involved ad ditional expense, and isfurthermore objectionable from its liability to become detached orloosened by use.

, The object of our invention is to produce a chamber that shall beself-draining, having a guide-cap orifice thrown in proper alignmentwith the barrel-axis, and adapted to form a durable rigid attachmentwithout a boss or brace, a boss or brace being necessary heretofore.

In the accompanying drawings, Figure l is an external View of a pumpembodying our invention, the middle portions being broken away forconvenience of representation. Fig. 2 is an axial section of the head orchamber at top of the pump-barrel. Fig. 3 represents a piece of sheetmetal cut or stamped to the form proper for the blank out of which suchhead or chamber is manufactured. Figs.

4 and 5 are sections of the head on the lines a" a: and y y,respectively.

A may represent a tube such as constitutes the shaft or barrel of anyfluid-pump. To such barrel there is permanently attached, by solderingor riveting, our improved head. or chamber 13, which is formed bybending a sheet-metal blank, such as shown in Fig. 3, into the form of aflattened triangular box or funncl,whose edges b I) and b b aredoubleseamed or lapped and soldered, leaving orifices b b b at itsrespective angles. Of the orifices, orifice 1) enables attachment to andcommunication with the pump-barrel, while orifice b affords a convenientplace of attachment for a screw-threaded neck, C, which receives theperforate guide or cap D. The orifice I)" serves asthe ventage or outletof a discharge spout or nozzle, B, which is a componentpart of and inone integral piece with the chamber proper, B. (See Figs. 1, 2, 4, and5.) The blank, Fig. 3, is so cut or stamped as to present the edges ormargin of the orifice b obliquely to the barrel, (instead ofhorizontally across, as heretofore.)

We claim as new and of our invention 1. Ablank for forming a pump-head,having edges 1) b b b, and recesses between the edges to form orificesZ) b I), as set forth.

2. A sheet-metal pump-head of triangular and spout-orifice b, as setforth.

In testimony of which invention we hereunto set our hands.
